Specification forming part of Letters Pat-ent'No. 214,548, datedOct-ober 4, 1861i. Y

ToA 'all whom it may concern.-

Be it known that L-O'soAR F. MoRRiLL, a

resident of Chelsea, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Apparatus for GeneratingHeat for Culinary or various other Purposes; and I do hereby declare thesame to .be fully described in the following specification, and rep#resented in the accompanying drawings, 'of

' which- Figure 1 isa top View, andl Fig. 2 a Vertical section, of suchapparatus.

My invention is iutendedfor the production of great heat from thecombustion of liquid hydrocarbons, particularly petroleum, or what isusually termed coal-oil or coalnaplr tha. Heretofore it'has beencustomary to mix air with a combustible gas or vapor, and to pass themixture through a foraminous diaphragm and burn it thereon, the resultbie-` ing a blue and non-illuminatingflame of great mixed and burnedwith the flame of the gas generated by the combustion ofa liquidhydrocarbon contained in the wick of an Argand lamp or burner. 4

l The nature of the Argand lamp iswell under- Stood, it being a lampwhose wick is tubular,

and when on lire is supplied .both internally and externally withcurrents of air.

In the drawings, A denotes an Argand lamp, of which a is thewickt`ubewhich is attached to the bgttom of the lamp-reservoir b, and isopen at both ends. l Itleads'out of the bottom of the lamp in order thatvwhen the lamp is in use air may rush freely into the lower end` of thetube and pass up through the tube and into thfelame of the wick cthereof. The

wick-tube a I surmount with what I term the internalair-currentforaminous dissemiuator, B, which is a hollow cylinder fitting into 'oron the tube and covered at topby a close or a foraminous cap, d, thesides of such cylinder being foraminous.- Another suchaircurrentdisseminator, C,vis or .may be applied to the lam-p, and so as tosurroundand 'extend above the, wick in manner. yas shown in thedrawings. This latter aerial current'disseminator is openat top, and itssidesare'foramil' nous. Furthermore, the' said-Argand lamp,-

wth its additions, as described,is .combined with .a stove or stand, D,orisarrahged-lwthin' My invention causes air to be tubularheat-interceptor, E, whose ides are foraminous or pertbrated in orderthat air for the externalsurface ofthe wick-flame' may pass through'such sides and into and up through the said interceptor. Thisheatinterceptor is for the purpose of arresting the heat radiatedlaterally from the flame of the wick, and causing such heat to passupward in orderthat it may be utilized to advantage. The wickmay havethe'usua'l appliances'for elevating or depressing it.

In the operation of my invention the air for the inner surface of theflame will 4be disseminated laterally into the flame and through thenumerous small orifices of the disseminatorB. This air, mixing with theflame or the combustible gaseous products resulting from' theliquid'that maybe contained in the wick, will aid in renderingsuch'iiamenon'luminous and of increased heating power. So, with respectto the action of the external aerial fo'raminous disseminator, C, theair for theouter surface of the dame will rush through' the meshes orine holes of such disseminator C and into the flame,v and 'by mingling.therewith will be burned with the gaseous products ofc'ombustion of theoilof the wickand aid in rendering such .dame nou-luminous and ofincreased heating power.

I am ,aware that `a perforated or. foralninous tube orvchimney has beenused `with an air and gas mixer as well as with an air and combustiblevapor-mixer, such as are .supplied with a foraminous diaphragm for themixture to iiow lthrough zand be l'burned on. Therefore I do not claimsuch as myinvention,

Aas there are between it and minelmaterial d'it 'ferenees inconstruction and operation, as in the carrying out of my invention orimpro`vement a wick and anArgandlamp become es-` sential thereto, suchbeing used to 'produce 'flame by the combustion of a liquidw hydrocarboncontained in the lamp and wfiek.` v The dame, instead ofbeing luminousandlof. little .heating power, is by the .numerous aerial jetsdischarged into it 'laterally changed into dal'ne not luminous, butpossessing largefheating powers-that is to say, there is so much oxygencombined with-the hydrogen and carbon when -burned in a iiuid` statethat combustion of the carbon becomes complete,a.nd'the result;-is'afgreat increase of heat with no smoke.' In' this way yhydrocarbons'mayf-be utilized for cooking purposes, as' well fas for generating heatfor various other purposes or uses, and I am enabled'to'entirelydispensewith the usual contrivance. em' loyed'lfo'r thelreductionjof a. hydrocarbon to avapor preparatorytobeing mixed vandcombined with' air.
